Through the implementation of the technical scheme, the invention can obtain the following technical effects:
through setting up the screening part of specific structure, drop on the screening board through the building stones after with the breakage, stir the rotation of rod through building stones, realize stirring the material above the screening board, strengthened the chance of building stones and screening hole contact to the screening effect has been strengthened greatly. Through set up sieve mesh clearance pole in the bottom, upwards remove through sieve mesh clearance pole, thereby can upwards ejecting with the plug in the sieve mesh, thereby reach the purpose of clearance sieve mesh, set up bold material discharge port on the screening board, carry out a period of back at the screening, open discharge port switching valve plate, continue to rotate building stones stirring roller, the effect that building stones stirred the rod this moment becomes through rotating the discharge that the bold material discharge port is complete with the thing on the board through the rotation by intensive screening, and the bold material of bottom is accepted the big lump material conveyer belt and is returned the bold material to broken intracavity and carry out further breakage, it is required until the particle diameter accords with the finished product. Thereby not only improving the efficiency of screening, having promoted the degree of consistency of screening building stones simultaneously.
Through setting up the stoving grinding part of specific structure, stainless wire net through the bottom is as supporting, the rotation of rotation abrasive disc through upper portion, the closed angle to the building stones has been realized carrying out the rounding, because the telescopic link can reciprocate, thereby can carry out the distance between the two of concrete adjustment according to the particle diameter of required building stones, simultaneously because set up spring holding chamber on the telescopic link, and stainless wire net also has certain elasticity simultaneously, thereby make the elastic pressure of pressure for having certain buffering between the two, thereby can not lead to the fact destruction to building stones granule main part when grinding, thereby the grinding effect has been reinforceed, the production of bad material has been avoided. Simultaneously because the bottom sets up is stainless steel screen, can leak down the mountain flour of granularity undersize, and through setting up hot dry air nozzle, reverse blow to stainless steel screen, can dry the building stones between stainless steel screen and the rotation abrasive disc, because of having certain water content wherein, some mountain flour can agglomerate, thereby can cause the reduction of yield, through the grinding between rotation abrasive disc and the stainless steel screen, the injection of the hot dry air of cooperation hot dry air nozzle, both realized dry effect to the building stones, also can strengthen the effect that the fragmentation leaked down with the mountain flour of agglomeration simultaneously, thereby the yield has been improved greatly.
Through the crushing sword that sets up three broken axle and interval set up, the cross motion through the crushing sword has realized the equal granularity breakage as far as possible of stone to broken yield has been improved. Because if the crushing sword temperature is too high among the crushing process, then its life of greatly reduced, consequently set up the water spout promptly in the entry storehouse, mix the water with the stone breakage to the water itself conducts heat and the water evaporates the heat absorption dual function and has realized the cooling effect of crushing sword, thereby has improved the life of crushing sword. The water body can not only realize the effect of cooling the crushing cutter in the stone production process, but also realize the effect of cleaning stone powder on the stone in the screening process, so that the stone powder is prevented from being bonded on the stone, most of the water body is filtered in the water filtering part, the effect of separating the water body (mixed with the stone powder) from the stone is realized, and the water body is further separated from the stone through the drying and grinding part, so that the effect of catalyzing the stone crushing and screening by the water body is realized (the catalysis is to accelerate the reaction speed and the reaction degree, but the water body of the invention weakens the crushing strength, strengthens the screening effect and efficiency, strengthens the separation of the stone powder and the stone, namely is similar to the catalysis effect in the whole device).
